citizen of thejUnited States, residing at .Vjandal1a, in the county ofl Fayette v'Stateof Illinois, have invented certain new and and lls'eful Improvements in Beating-Enfollowing is a specification.'

The'primary object of the invention is the for raising or lowering, by power, tlzlesupporting means for the beatingdrum of roll. i

' In-the operation of beating engines acting u on rags and other'materials in the man acture of paper, when the vat or tank 1is .iirst charged, the roll or vdrum is ralsed height aboveto a .predetermined maximum thebed plate. As the material is comminuted, the beating drum is gradually lowered, to 4more nally reduce the mass. To accom- I have combined and arranged the hereinafter described mechanisms in novel'forms to increase the efficiency oftheinachine, and to save time and labor.`

In the accompanying 'drawings illustrated one complete example of the physical embodiment o f my invention con.

Fig. 2 is an end view of so much of the as is necessary to illus- Fig. 3 is a plan view of part of the mechanism of Fig. 1, enlarged. In the preferred embodiment of my inillustrated in `the drawings utilize the usual drum or vat 1 having the central or mid-feather@ around which lthe stockpasses as usual.

For rotating the countershaft from the open belt a clutch member 13 is revoluble loosely on the countershaft, and for revolving the countershaft in a reverse direction, the clutch member 11 is employed. These clutch members are' actuated through the medium of 15 which is keyed to the countershaft, and 4may be shifted through the forked lever 15 and shift rod 16. At each end of the countershaft 9 it 1s provided with a worm screw'll andthe ends .of the shaft are supported in'bearing brackets 18 supported from the post 19 of the supporting frame. v

'A horizontally revoluble worm wheel 20 is arranged adjacent to and-meshes with each worm 17. Each wheel has a hub 25, which is held by a pin 24, against dislocationin a vertical direction,

adjusting screw bar 21 wheel and this bar may be raised or lowered through the action of its wheel.

At its lower end the bar is provided with a hook 22, complementary to the hook 23 on the end of the arm hook on the bar the free end of the pivoted arm is suspended.

An indicating device is provided, to show and for this purpose a pointer 26 located on the screw bar coacts with a pointer 27 which, through the medium of the holder or sleeve 28 and screw 29, is held in adjusted position on frame of ther-od 80 which is fixed on the the engine. t

The mode of operation will be evident, and an extended description is unnecessary. When it is desired to adjust the position of the beating drum, the pointer 27 is movedto a predetermined position on the rod or post 30, and the position of the drum may be determined thereafter by therelationship.
